"We look at all the symptoms and usually recommend cold and flu medication, cough treatment depends whether the person has a dry or phlegmy one and a range of throat lozenges are also available," he said.

"As a naturopath I strongly believe in the effectiveness of vitamins and herbs like echinacea, vitamin C and garlic.

"It is well known that a high dose of vitamin C will shorten the duration of a viral cold or flu."

Both health professionals believe in the power of eating right, getting enough sleep and rest so your body can heal, and drinking lots of water.
